imagePixel()

Description

Gets the color of an individual pixel from a PImage. Must have used one of the advanced image functions and set the copyPixelData bool to true.

Parameters

imagePixel(PImage img, float x, float y)

• img - (PImage) The image to check a pixel in
• x - (int) The x coordinate of the pixel in the image.
• y - (int) The y coordinate of the pixel in the image.

Example

PImage justin_face;
PImage tinted_justin_face;
int x_size, y_size;

void init()
{
  justin_face = loadImageAdvanced("./Assets/justin1.png", true, false);

  x_size = imageWidth(justin_face);
  y_size = imageHeight(justin_face);

  // Tint the image with the color of a random pixel in the image
  int x_pixel = randomRangeInt(x_size/2, x_size);
  int y_pixel = randomRangeInt(y_size / 2, y_size);
  PColor pixel_color = imagePixel(justin_face, x_pixel, y_pixel);
  tinted_justin_face = imageCreateTint(justin_face, pixel_color);
}

void update()
{
  background(color(255, 255, 255, 255));
  image(tinted_justin_face, mouseX, mouseY, x_size, y_size, 255);
}
